Investment Category-Focused Criteria

1. Define High Growth Area Need: Provide a narrative to explain how proposed project is needed to serve a high growth where project is located. (Please provide quantifiable data that demonstrates high growth in population, employment, commercial development or daily traffic.)

The project is located in a high growth area. The population is projected to grow by 81.3% and jobs are projected to increase by 142.8%. A multifamily housing land use change off of Garden Rd, south of the project is planned. This section of FM 518 is congested. In the 2022 report 100 Most Congested Roadways in Texas by the Texas Transportation Institute, the annual total delay per mile on the segment is 101,640 person hours. The current daily volume of traffic on the segment is roughly 27,047, of which 1.7 percent are trucks. By 2041 daily traffic volume is expected to increase by 40 percent. The purpose of the project is to improve capacity, connectivity, level of service, and safety of the project segment. The added capacity will improve regional connectivity for all modes while also reducing congestion and improving safety by reducing primary and secondary crashes due to congestion and by bringing the segment of FM 518 up to TxDOT and FHWA safety standards.

2. Is the proposed project recommended in a statewide, regional, or local plans?

Yes

2a. If yes, please provide link to the plan.

3. Please provide proposed project description (detailed project scope).

This project will widen from 4-lanes to 6-lanes. A raised median will be included and may vary between 14 and 18 feet. Convert the existing open ditch drainage system to a curb and gutter drainage system. In addition, outside pedestrian sidewalks and bikeways are proposed.

3a. Does the project provide access to new planned land use development (residential or commercial), or connects existing discontinuous networks?

Yes

3a-i. If yes, explain.

The project is located in a high growth area that is highly commercialized/retailed based. The population is projected to grow by 81.3% and jobs are projected to increase by 142.8%. A multifamily housing land use change off of Garden Rd, south of the project is planned.

3b. Does the project expand existing networks to alleviate anticipated congestions?

Yes

3b-i. If yes, explain.

This project will add capacity. Adding capacity will relieve congestion on the facility by allowing for a reduced vehicle to capacity ratio. Further, it will allow more room for traffic to avoid crashes on the segment, reducing congestion caused by crashes. It will also add medians. As an access management strategy in corridors, medians reduce mid-block left turn related crashes. They enhance traffic flow and reduce the quantity and severity of crashes at intersections and resulting congestion.

3b-ii. What is the estimated Level of Service after the project is completed.

LOS C

4. Does the proposed project provide an alternative route to existing corridor (Road or commuter transit)?

Yes

4a. If yes, explain.

This route provides east-west connectivity through Pearland, parallel to Magnolia Pkwy, Bailey Rd, and McHard Rd, all of which can be used as alternate routes to each other in case of inoperability.

5. Is the proposed project located on a facility identified as a hurricane evacuation route in any regional or local plans?

5a. If no, is the proposed project located on a facility that functions as an alternative to an evacuation route?

Yes

5a-i. If yes, explain.

Yes

2. Please provide a narrative explaining how the proposed project improves traffic operations. Within the narrative, please include if the proposed project includes construction of truck only lanes or managed truck only lanes, construction of an interchange, or intersection improvements.

This section of FM 518 is congested. In the 2022 report 100 Most Congested Roadways in Texas by the Texas Transportation Institute, the annual total delay per mile on the segment is 101,640 person hours. The current daily volume of traffic on the segment is roughly 27,047, of which 1.7 percent are trucks. By 2041 daily traffic volume is expected to increase by 40 percent. The purpose of the project is to improve capacity, connectivity, level of service, and safety of the project segment. The added capacity will improve regional connectivity for all modes while also reducing congestion and improving safety by reducing primary and secondary crashes due to congestion and by bringing the segment of FM 518 up to TxDOT and FHWA safety standards.

3. Please provide a narrative explaining how the proposed project improves walking and biking conditions. Within the narrative, please explain if the proposed project scope includes construction of a new or improved existing bicycle and pedestrian infrastructure on a project facility or in the vicinity of the project.

Sidewalks will be build on this project according to the 2018 schematic. The addition of sidewalks will create transportation alternatives and allow pedestrians greater access to services and improve quality of life.

4. Please provide a narrative explaining how the proposed project improves traffic conditions for transit services (local, express, signature, or commuter).

No existing or planned transit service is provided on this facility. The Pearland Transit Needs Assessment and Plan study is starting soon by H-GAC but no transit recommendations yet as of yet.

5. Please provide a narrative explaining how the proposed project will reduce inoperability for significant periods due to infrastructure damaged by a collision with vehicles such as trucks, ships, and barges.

The project will widen lanes to allow more space to move disabled vehicles and to better maintain flow on the facility after vehicle collisions.

6. Please provide a narrative explaining how the proposed project will improve state of good repair and extend the service life of the project facility.

No HPMS condition data is currently available for this project. However, in a widening/reconstruction project like this project, pavement is removed and new pavement is constructed, thus increasing the state of good repair and extending the service life of the facility.

Planning Factors Criteria

1. What is the existing fatality crash rate at the project location? Regional crash data is available online on the crash data viewer. H-GAC staff will provide assistance in calculating the crash rates upon request.

2. What is the existing serious injury crash rate at the project location? Regional crash data is available online on the crash data viewer. H-GAC staff will provide assistance in calculating the crash rates upon request.

7.306

3. Please provide a narrative explaining how the proposed project reduces expected fatality and serious injury crashes. Narrative must include specific improvements (work types) included in the project scope. Crash reduction factors associated with specific work types can be found in the safety benefits calculation template. H-GAC staff can provide assistance in gathering the crash reduction factors upon request.

The Crash rates for this segment are per 100 million vehicle miles traveled. The fatality rate is 0, lower than the regional average (1.23), and the serious injury rate is 7.306, higher than the regional average (6.18). The widening of the roadway will provide additional capacity to the roadway and reduce primary and secondary crashes caused by congestion. Including medians reduces the quantity and severity of crashes at intersections and provides refuge to crossing pedestrians. As an access management strategy in corridors, medians reduce mid-block left turn-related crashes. They enhance traffic flow and can be used as part of a traffic calming strategy to reduce speed. The addition of pedestrian infrastructure will allow cyclists and pedestrians to safely use the facility and reduce points of conflict with vehicles, thus improving the overall safety of the segment. The consolidated crash reduction factor for this project is 168%, as a result of the inclusion of medians (WC 203), installing sidewalks (WC 407), drainage improvements (WC 209), and the addition of through lanes (WC 517).

3. Please provide a narrative explaining how the proposed project provides benefits to vulnerable populations. Benefits include safety improvements, construction of or improvements to ped/bike facilities, or improvements to transit stops.

The area surrounding the project segment has a lower low-income population (3.51%) as compared to the regional average of 13.5%. The area surrounding the project segment has a lower minority population (58.5%) as compared to the regional average of 65% minority. Because of its central location in the regional network, the project will produce improvements in mobility and connectivity for vulnerable populations as well as connectivity to schools, medical facilities, and social services for the regional population. The project will improve drainage to ATLAS-14 standards, which reduce flooding events and their impact on vulnerable populations. As a result of the improvement, vulnerable populations will have increased resilience and evacuation capacity in the event of hazards.

4. Please provide a narrative explaining how the proposed project avoids or mitigates adverse effects to vulnerable populations. A list of adverse effects was provided in detailed criteria document.

The area surrounding the project segment has a lower low-income population (3.51%) as compared to the regional average of 13.5%. The area surrounding the project segment has a lower minority population (58.5%) as compared to the regional average of 65% minority. TxDOT’s Environmental Process is designed to ensure compliance with Title VI of the Civil Rights Act of 1964, and the Executive Order on Environmental Justice. Standard practice is to implement projects that provide user safety and operational efficiency while taking into account environmental quality and impacts to surrounding communities. In practice this means identifying and assessing potential project impacts, then proposing measures to avoid, minimize and/or mitigate disproportionately high and adverse effects to Environmental Justice Populations. For example, the project will improve drainage to ATLAS-14 standards, which will mitigate impacts from added capacity to vulnerable populations.

Impacts on Natural and Cultural Resources

1. Please provide a narrative explaining how the proposed project avoids or mitigates impacts to natural (flood plains, wetlands) and cultural (historic and archeological sites) resources. H-GAC staff can provide assistance in identifying natural and cultural resources located within a quarter mile buffer of the project location.

This project received a Finding of No Significant Impact (FONSI) in 2020. Through the development of an Environmental Assessment, TxDOT has determined there will be no significant impacts to natural or cultural impacts as a result of the project. The study noted that the preferred alternative was selected from among 4 build alternatives because it resulted in the fewest residential, business, and other displacement or relocation impacts, the least impact to waters of the US, and the smallest ROW acquisition in the project area. The required displacements for the preferred alternative are 4 residences and 10 commercial facilities.
